Answer:
He must earn $2,400 to cover both leisure and $2,160 for school expenses.
Step-by-step explanation:
Let the total amount Ken must earn be k. Then 10% of that would cover leisure activities and the remaining 90% specifically for school expenses.
Then 0.90k = $2,160, and k = $2,400.
He must earn $2,400 to cover both leisure and $2,160 for school expenses.
Tan^2x + 1 + tanx - 3 = 0 tan^2x + tanx - 2 = 0 (tanx + 2)(tanx - 1) = 0 tanx = -2 or tanx = 1 x = 2.034 radians or x = 5.176 radians or x = pi/4 radians or x = 5pi/4 radians

Answer:
Choice D
Step-by-step explanation:
(x-1)²
- =(x-1)(x-1)
- =x*x+x*−1+-1*x+-1*-1
- =x²−x−x+1
- =x²−2x+1
Choice D is accurate.
Answer:
y=
Step-by-step explanation:
There are three letters A, B, C in order to make the tags and y is the number of tags that can be made using n spaces. So, there are three choices for the first letter A and three choices for the remaining two letters that are B and C respectively.
By the basic counting principle,
Formulae for the number of tags they can make using n spaces is: 3×3×3×3×..........×3( n times)
=
Therefore, y=
